Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625698, here are decompositions:

17 + 31625681 = 31625698
47 + 31625651 = 31625698
131 + 31625567 = 31625698
191 + 31625507 = 31625698
317 + 31625381 = 31625698
347 + 31625351 = 31625698
641 + 31625057 = 31625698
659 + 31625039 = 31625698

Showing the first eight; more decompositions exist.
